In the scope from the latter half of rearward end to secured core 5 of magnetic cylindrical body 4, form plastic coating 34 at their outer circumferential face by die forming, this coating 34 is used for embedding coil assembly body 28 and solenoid housing 31.At this moment, be used for taking in, to keep described joiner terminal 33 and integrally formed with coating 34 to one of coil assembly body 28 side-prominent joiner 35.
In Fig. 2 and Fig. 3, secured core 5 has the hollow portion 19 that links to each other with the inside of fuel inlet tube 9, and the front-end face of the ring-type of this secured core 5 becomes suction surface 5a.Movable core 12 is by as the magnetic circuit forming portion 12a of the ring-type of its peripheral part, constitute as the fuel passage forming portion 12b of the ring-type of radial direction intermediate portion and as the valve rod joint 12c of central part.The magnetic circuit forming portion 12a of this ring-type has: with the sucking action face 12a' of the opposed ring-type of suction surface 5a of the ring-type of secured core 5; With with the opposed outer circumferential face of inner peripheral surface of described magnetic cylindrical body 4 and non-magnetic cylinder body 6, the front surface of this magnetic circuit forming portion 12a forms the funnelform concave surface 18 towards the place ahead hole enlargement.The mode that the outermost shape of the magnetic flux f that this concave surface 18 circulates movable core 12 in with coil 30 energising the time conforms to forms, and this concave surface 18 is made of frusto-conical face.
In fuel passage forming portion 12b, be provided with a plurality of fuel through- holes 20,20 that are communicated with the hollow portion 19 of secured core 5 with the state of arranging in the form of a ring around valve rod joint 12c ..., the root of described valve rod 13 is connected with valve rod joint 12c.This valve rod 13 can be integrally formed with same material and movable core 12, also can be fastened on the central part of movable core 12 with the valve rod 13 that other materials is shaped by be pressed into or welding etc.
Be supported on the collar 12j of ring-type of the inner peripheral surface of magnetic cylindrical body 4 in the outer circumferential face of movable core 12 be formed with to slide freely mode.Therefore, valve assembly body V is being supported sliding freely with the chimeric valve bullport 15 of spool 14 with chimeric magnetic cylindrical body 4 these two points away from each other of the collar 12j of movable core 12, thereby can make the switching stable posture of valve assembly body V.
Ear end face depression at the fuel passage forming portion 12b of movable core 12 is provided with circular spring seat 24.And, be pressed into the tubulose retainer 23 of band grooving at the hollow portion 19 of secured core 5, between this retainer 23 and described spring seat 24, compress and be provided with valve spring 22,22 pairs of movable cores 12 of this valve spring close the valve side application of force to spool 14.At this moment, adjust the setting load of valve spring 22 with respect to the chimeric degree of depth of hollow portion 19 by retainer 23.
Be welded with the jet tray 10 of steel plate system at the front-end face of valve base part 3 liquid-tightly, described jet tray 10 have with the outer end of valve opening 7 mutually in the face of and diameter than the big fuel explosion chamber 25 of valve opening 7 and a plurality of fuel jet orifices 11,11 that this fuel explosion chamber 25 is opened wide to the outside ...
And, form the seal groove 41 of the ring-type that is useful on sealed members 40 such as assembling O type circle in the periphery of the rearward end of fuel inlet tube 9.The front bulkhead of sealing groove 41 is made of the flange 42a of the rear end of the plastic collar 42 of the anterior outer circumferential face that is pressed into fuel inlet tube 9, and the aft bulkhead of sealing groove 41 is made of the mounting flange 43a of the fuel filter 43 of the entrance that is pressed into fuel inlet tube 9.Rearward end periphery at this fuel inlet tube 9 is embedded with not shown fuel feed pipe, and described sealed member 40 closely contacts with the inner peripheral surface of described fuel feed pipe.
Then, the effect to this embodiment describes.
Never illustrated petrolift is sent to the fuel under high pressure of fuel inlet tube 9 after being filtered by fuel filter 43 via not shown fuel feed pipe, be full of the inside of valve pocket 2, namely be full of the inside of fuel inlet tube 9, the hollow portion 19 of secured core 5, the fuel through- hole 20,20 of movable core 12 ..., non-magnetic cylinder body 6, magnetic cylindrical body 4 and valve base part 3 inside etc.And then, under the state of coil 30 demagnetizations, by the active force of valve spring 22 valve assembly body V is forwards pushed, make spool 14 be seated at valve seat 8 and valve opening 7 is closed.
When carrying out excitation by energising and to coil 30, consequent magnetic flux passes solenoid housing 31 successively, magnetic cylindrical body 4, movable core 12, secured core 5, solenoid housing 31, utilization is at two iron cores 5, the magnetic attraction that produces between 12 makes movable core 12 overcome the setting load of valve spring 22 and iron core 5 attractions that are fixed, spool 14 leaves from valve seat 8, thereby valve opening 7 opens wide, the fuel under high pressure that is full of valve base part 3 inside flows out and spreads to radial direction at fuel explosion chamber 25 from valve opening 7, and from a plurality of fuel jet orifices 11,11 ... firing chamber or gas-entered passageway to the not shown internal-combustion engine that is equipped with this Fuelinjection nozzle I spray.
In addition, the front surface of the magnetic circuit forming portion 12a of the ring-type of movable core 12 forms funnelform concave surface 18 towards the place ahead hole enlargement in the scope from its axial intermediate portion to front end, therefore, the exterior lateral area of the magnetic flux f that this concave surface 18 circulates in magnetic circuit forming portion 12a when switching on coil 30 conforms to, both fully guaranteed the useful area of the magnetic circuit in the movable core 12, can alleviate the weight of movable core 12 again, the weight that alleviates is corresponding with the vacancy part of the inboard of above-mentioned concave surface 18.The guaranteeing of the useful area of the magnetic circuit of such movable core 12 combines with weight saving, can realize the improvement of the switching responsiveness of movable core 12 and then spool 14.And the weight saving of movable core 12 makes the use amount of its material reduce, and therefore also is conducive to the reduction of cost.
And described funnelform concave surface 18 is made of frusto-conical face, and thus, it is easy that the shaping of this concave surface 18 or cutting become.
And, the valve rod 13 of supporting spool 14 is connected with the central part of movable core 12, in the mode of surrounding valve rod joint 12c, namely the mode of surrounding valve rod 13 arranges a plurality of fuel through-holes 20, described fuel through-hole 20 is communicated with the hollow portion 19 of secured core 5 between the described magnetic circuit forming portion 12a of described valve rod 13 and ring-type, thereby in the useful area of magnetic circuit that can be in guaranteeing movable core 12 fuel of big flow is flow in the movable core 12.
Then, second mode of execution of the present invention shown in Figure 4 is described.
In this second mode of execution, the funnelform concave surface 18 of the magnetic circuit forming portion 12a of movable core 12 is made of the flexure plane of heaving towards axial intermediate portion.Other structure is identical with aforementioned embodiments, therefore in Fig. 4 to being marked with identical reference number with the corresponding part of aforementioned embodiments and the repetitive description thereof will be omitted.
According to this second mode of execution, the flexure plane that constitutes funnelform concave surface 18 conforms to more with the exterior lateral area of the magnetic flux f of movable core 12, has correspondingly increased the inboard volume of this concave surface 18, can further realize the weight saving of movable core 12.
More than, embodiments of the present invention have been described, yet the present invention be not limited thereto, can in the scope that does not break away from its purport, carry out various design alterations.
